Question

3600 powder packets of size 5cm x 4cm x 3 each can be placed in a cubical box. find the size of box

Answer 1

2 ways

Method 1

160 is divisable be 8 160 / 8 =20. Therefore the box will be full so divide the volume of the box by the volume of a packet.

Volume of box is 160^3

Volume of one packet is 8^3

No. of packets that will fit in the box is (160 ^3)/(8^3) = 8000

Alternate Method

Since the packets are stacked 20 x 20 x 20

No. of packets is 20 x 20 x 20 = 8000
